Audio Vs MIDI recording - newbie question
So I’m relatively new to iOS recording and one thing that confuses me is the fact that most software instruments can record as both MIDI and audio. I fully understand the difference between the two, and the editing possibilities of MIDI vs audio, but the last time I was recording regularly the lines between MIDI and Audio were much clearer: if the sound was generated by the computer/soundcard it was MIDI, anything else was audio.
Besides the different editing possibilities and the opportunity to sample audio, what are the main reasons for recording an AU instrument as MIDI or audio?
Is there much difference in CPU use?
